Abstract
A liquid crystal display device includes a pair of opposite substrates, and a liquid crystal layer as a display medium disposed between said substrates. The pair of substrates are adhered together by a resin sealing material disposed on the periphery portion of at least one of the substrates at the prescribed gap, and an outflow preventing portion having a plurality of concave portions is provided so that at least a part of the outflow preventing portion overlaps with the sealing material.
Claims30
A liquid crystal display device, comprising a pair of opposite substrates, and a liquid crystal layer as a display medium disposed between said substrates,
- wherein said pair of substrates are adhered together by a resin sealing material disposed on the periphery portion of at least one of said substrates at the prescribed gap, and
- wherein an outflow preventing portion having a plurality of concave portions is provided so that at least a part of said outflow preventing portion overlaps with said sealing material.
A process for producing a liquid crystal display device, comprising the steps of:
- forming an outflow preventing portion on the prescribed location of one of a pair of substrates;
- disposing a sealing material on the prescribed location of the other substrate;
- adhering said substrate having said outflow formed thereon to said substrate having said sealing material disposed thereon so as not to overlap said outflow preventing portion with said sealing portion;
- and
- pressing said pair of the adhered substrates to deform said sealing material into a compressed shape, and overlapping at least a part of said outflow preventing portion with said sealing material when the gap of said substrates reaches the prescribed gap.
A liquid crystal display device, comprising:
- a first substrate having a switching element, an interlayer insulating film formed on said switching element, and a pixel electrode formed on said interlayer insulating film;
- a second substrate adhered together to the first substrate a sealing material at the prescribed gap;
- and
- a liquid crystal layer disposed in a space defined by the first and second substrates and said sealing material;
- wherein an adhesion reinforcing portion is provided in at least a part of said interlayer insulating film contacting said sealing material.
A liquid crystal display deice, comprising:
- an active matrix substrate having a plurality of scanning lines and signal lines crossing each other, a display pixel provided in a region surrounded by the adjacent scanning lines and adjacent signal lines, a switching element corresponding to said display pixel, said switching element receiving a scanning signal from said scanning lines and an input signal from said signal line, an interlayer insulating film covering said lines and said switching element, and a pixel electrode provided on said interlayer insulating film corresponding to said display pixel;
- a counter substrate having a counter electrode opposite to said pixel electrode and adhered to said active matrix substrate by a sealing material at the prescribed gap;
- and
- a liquid crystal layer disposed in a space defined by said active matrix substrate, said counter substrate electrode and said sealing material;
- wherein an adhesion reinforcing portion is provided in at least a part of said interlayer insulating film contacting said sealing material.
A liquid crystal display deice, comprising:
- an active matrix substrate having a plurality of scanning lines and signal lines crossing each other, a switching element provided in a matrix shape, said switching element receiving a scanning signal from said scanning lines and an input signal from said signal line, and a pixel electrode provided corresponding to said switching element;
- a color filter substrate having color filter layers and a black matrix and adhered to said active matrix substrate by a sealing material at the prescribed gap;
- and
- a liquid crystal layer disposed between said active matrix substrate and said color filter substrate,
- wherein an interlayer insulating film is provided between said lines and said pixel electrode and in a region including a region having said sealing material disposed.
A process for producing a liquid crystal display device, comprising the steps of:
- forming an interlayer insulating film using a photosensitive resin material;
- and
- exposing the prescribed portion of said interlayer insulating film with a prescribed exposure amount of light and developing said portion, so as to form an outflow preventing portion.
